Tillverkning av medeltida ugnskakel i Stockholm och Uppsala – Ett meddelande om fynd från undersökningarna vid Slussen

Abstract

As early as the late Middle Ages, the tiled stove was used as a source of heating, albeit only in the most prestigioussettings. Late medieval stove tiles have been found in very few places in Stockholm and mainly in high-status environments. The recent excavations at Slussen have uncoveredseveral new finds of medieval stove tiles.During the 15th century, exclusive tiles of the same type was produced in Central Europe. However, 19th century finds of matrices, indicate that there may have been a domestic production of exclusive tiles as early as the end of the 15th century. The earliest written record of a potter in Stockholm dates to 1479, and thus a local production of stove tiles is probable as well.However, whether the late medieval tiles were imported or made locally from imported matrices has not yet been established. A recent ICP-analysis of the clay in medieval stove tiles found at Slussen has now ascertained their provenance to both Stockholm andUppsala. The results can further contribute to the discussion on trade and crafts exchange in Hanseatic Europe.
